Abstract
A blister package is disclosed that comprises a blister layer having an article receiving blister formed therein for holding medicaments, and a base layer. The blister layer has one or more tearing blisters formed therein and the blister layer is joined to the base layer except in the areas of the article receiving blister and the tearing blisters. The base layer and the blister layer are joined such that opening the blister package to access the medicament requires tearing through one of the tearing blisters and the article receiving blister. The tearing blisters preferably extend from one or more outer edges, which may include the corners, of the blister layer toward said article receiving blister. The portions of the base layer and the blister layer that are joined together cannot be readily torn from the outer edges of the blister package, but the portion of the blister layer that forms the tearing blister is thin enough that the tearing blister and the portion of the base layer under the tearing blister can be readily torn from the outer edge of the blister package.
